DESCRIPTION OF EMBODIMENTS First Embodiment

FIGS. 1A and 1B are perspective views illustrating an appearance of a mobile phone device 100A according to a first embodiment of the present disclosure. The mobile phone device 100A according to the present embodiment is a smartphone. Note that the mobile phone device 100A may be a mobile phone other than a smartphone or may be a portable information processing device having a call function. Furthermore, in the following description, it is assumed that the first user uses the mobile phone device 100A to talk with the second user who is a user of another phone device.

As illustrated in FIGS. 1A and 1B, the mobile phone device 100A includes housings 41 and 42 and a hinge 49. Each of the housings 41 and 42 is a housing having a rectangular parallelepiped plate shape. The housing 41 has a rectangular display surface 41S on one of the front and back two surfaces, and the housing 42 has a rectangular display surface 42S on one of the front and back two surfaces. The display surfaces 41S and 42S are display surfaces of a display device 14 (see FIG. 2 ) included in the mobile phone device 100A. In the present embodiment, the display surfaces 41S and 42S have the same display area. In addition, the housing 41 is provided with a speaker 16 and a microphone 17. The speaker 16 and the microphone 17 are used, for example, when the first user uses the mobile phone device 100A to talk with the second user.

An end surface 41E is one of two end surfaces on the long side of the front and back two surfaces of the housing 41 among four end surfaces. Similarly, the housing 42 has four rectangular end surfaces surrounding the front and back two surfaces thereof. An end surface 42E is one of two end surfaces on the long side of the front and back two surfaces of the housing 42 among the four end surfaces. The hinge 49 is a so-called hinge that rotatably connects the housings 41 and 42. The hinge 49 connects a long side opposite to the long side facing the display surface 41S on the end surface 41E and a long side opposite to the long side facing the display surface 42S on the end surface 42E.

In the present embodiment, the hinge angle formed by the display surfaces 41S and 42S changes as the hinge 49 rotates. In the present embodiment, by setting the hinge angle to 360 degrees to cause the display surfaces 42S and 41S to face outward as illustrated in FIG. 1A, the first user can bring the display state of the display device 14 of the mobile phone device 100A into a first display state in which display is performed only on the display surface 41S. In addition, by setting the hinge angle to 180 degrees, the first user can cause the display surfaces 41S and 42S to face the first user as illustrated in FIG. 1B. By this operation, the display state of the display device 14 of the mobile phone device 100A becomes a second display state in which display is performed on both the display surfaces 41S and 42S. The display area in the second display state is larger than the display area in the first display state.

FIG. 2 is a block diagram illustrating a hardware configuration of the mobile phone device 100A. As illustrated in FIG. 2 , the mobile phone device 100A is a computer including a processing device 11, a storage device 12, a communication device 13, the display device 14, an operating device 15, the speaker 16, the microphone 17, and an opening/closing detection device 18. The respective elements of the mobile phone device 100A are connected to each other by a single or a plurality of buses. Note that the term “device” in the present application may be replaced with another term such as a circuit, a device, or a unit. In addition, each element of the mobile phone device 100A includes one or a plurality of devices, and some elements of the mobile phone device 100A may be omitted.

The processing device 11 is a processor that controls the entire mobile phone device 100A, and includes, for example, one or a plurality of chips. The processing device 11 includes, for example, a central processing unit (CPU) including an interface with a peripheral device, an arithmetic device, a register, and the like. Some or all of functions of the processing device 11 may be implemented by hardware such as a digital signal processor (DSP), an application specific integrated circuit (ASIC), a programmable logic device (PLD), or a field programmable gate array (FPGA). The processing device 11 executes various types of processing in parallel or sequentially.

The storage device 12 is a recording medium readable by the processing device 11, and stores a plurality of programs to be executed by the processing device 11 and various data to be used by the processing device 11. The plurality of programs includes a control program PR. The various types of data include a table TBL. The storage device 12 includes, for example, a nonvolatile storage circuit such as a read only memory (ROM), an erasable programmable ROM (EPROM), or an electrically erasable programmable ROM (EEPROM), and a volatile storage circuit such as a random access memory (RAM).

FIG. 3 is an explanatory diagram illustrating stored contents of the table TBL. The table TBL stores data of a so-called telephone directory. As illustrated in FIG. 3 , the table TBL stores a plurality of records r. One record r is a set of a phone number and a name. The name includes a nickname, a name, and a designation. The names include “first name”, “surname”, “name”, “company name”, “trade name”, and “facility name”.

The communication device 13 is a device that communicates with another device via a communication network such as a mobile communication network or the Internet. The communication device 13 is also referred to as, for example, a network device, a network controller, a network card, or a communication module. For example, an application program received by the communication device 13 from a distribution server (not illustrated) via a communication network is stored in the storage device 12. Furthermore, the communication device 13 includes a wireless device that performs short-range wireless communication such as Bluetooth (registered trademark). In addition, the communication device 13 outputs communication information indicating a communication status to the processing device 11. The communication status includes a call made to another phone device, an incoming call from another phone device, and establishment of communication with another phone device.

The display device 14 displays various images on the above-described display surfaces 41S and 42S under control by the processing device 11. For example, various display panels such as a liquid crystal display panel and an organic EL display panel are suitably used as the display device 14. A display device having the display surface 41S and a display device having the display surface 42S are physically separate display devices. However, in the mobile phone device 100A according to the present embodiment, one image may be displayed across the display surfaces 41S and 42S, or display by the display surface 41S and display by the display surface 42S may be linked with each other to execute one combined process. Therefore, in the present embodiment, the display device having the display surface 41S and the display device having the display surface 42S are treated as one display device 14.

In addition, the display device 14 can switch the display state between the first display state and the second display state in which the display area is larger than the display area in the first display state.

The operating device 15 is a device for inputting information to be used by the mobile phone device 100A. The operating device 15 receives an operation by a user. Specifically, the operating device 15 receives an operation for inputting signs such as numbers and characters, and an operation for selecting an icon to be displayed on the display device 14. For example, a touch panel that detects contact with the display surface of the display device 14 is suitable as the operating device 15. Note that the operating device 15 may include a plurality of operators that can be operated by the user. The first user can input a phone number of another phone device used by the second user by using the operating device 15.

The speaker 16 is a device that converts an electric signal into sound. The processing device 11 includes a DA converter, and an analog signal obtained by converting a digital signal by the DA converter is supplied to the speaker 16. Alternatively, a DA converter may be provided at a previous stage of the speaker 16. In this case, the processing device 11 outputs audio data to the DA converter. When the first user uses the mobile phone device 100A to talk with the second user, the speaker 16 outputs a voice of the second user. In the example illustrated in FIG. 1A, the speaker 16 is provided in an upper portion of the display device 14, but the present disclosure is not limited thereto. For example, a first speaker may be provided in the upper portion of the display device 14, and a second speaker may be provided in a lower portion of the display device 14. When the two speakers are provided, the speaker 16 is a general term for the first speaker and the second speaker.

The microphone 17 is a device that converts sound into an electric signal. The processing device 11 includes an AD converter. The processing device 11 converts an analog audio signal output from the microphone 17 into digital sound data by the AD converter, and uses the sound data for processing. Alternatively, an AD converter may be provided at a subsequent stage of the microphone 17. In this case, the audio signal is converted into audio data by the AD converter. The audio data is supplied to the processing device 11. When the first user uses the mobile phone device 100A to talk with the second user, a voice of the first user is input to the microphone 17.

The opening/closing detection device 18 is a device that detects a display state of the display device 14. Specifically, the opening/closing detection device 18 includes a sensor that detects an angle formed by the display surfaces 41S and 42S, that is, a hinge angle of the hinge 49 and outputs a detection signal having a magnitude corresponding to the hinge angle. When the hinge angle θ indicated by the detection signal is within the range of, for example, 360° < θ < 270°, the opening/closing detection device 18 detects that the display state of the display device 14 is the first display state (closed state). When the hinge angle θ indicated by the detection signal is within the range of, for example, 270° < θ < 90°, the opening/closing detection device 18 detects that the display state of the display device 14 is the second display state (open state). The opening/closing detection device 18 outputs detection information 18 a indicating a result of the detection to the processing device 11.

The processing device 11 reads the control program PR stored in the storage device 12 and executes the read control program PR to implement various functions. FIG. 4 is a block diagram illustrating the functions of the processing device 11.

The processing device 11 functions as a communication unit 110A, an image generation unit 120A, a detection unit 130, and a display control unit 140 by executing the control program PR.

The communication unit 110A executes a call between the first user of the mobile phone device 100A and the second user by using the communication device 13, the speaker 16, and the microphone 17. Call modes include a normal call and a hands-free call. The normal call is a mode in which the first user presses the mobile phone device 100A against his/her face to make a call. The hands-free call is a mode in which the first user places the mobile phone device 100A away from his/her face to make a call. When the call mode is the hands-free call, the communication unit 110A increases the loudness of the sound output from the speaker 16 as compared with a case where the call mode is the normal call. Specifically, the communication unit 110A controls the amplitude of an audio signal supplied to the speaker 16 according to the call mode.

Further, the communication unit 110A outputs identification information ID for identifying another phone device used by the second user. Details of the identification information ID will be described later.

The image generation unit 120A generates a first image D1 and a second image D2. When the first user makes a call with the second user, the first image D1 indicates first information including the phone number of another phone device. In a case where the image generation unit 120A generates the first image D1, the image generation unit 120A acquires the identification information ID for identifying another phone device from the communication unit 110A. The identification information ID is, for example, the phone number of another phone device. The identification information ID may be, for example, a name of the second user. Alternatively, the identification information ID includes at least one of the phone number of another phone device and the name of the second user. The identification information ID in the present embodiment includes the phone number of another phone device and the name of the second user. The communication unit 110A identifies the name of the second user by referring to the table TBL based on the phone number of another phone device, and generates the identification information ID including the phone number and the name of the identified second user.

FIG. 5 is a plan view illustrating an example of the first image D1 displayed on the display surface 41S of the display device 14. In the first image D1 illustrated in FIG. 5 , an image of text indicating the second user is arranged in a region A11, an image of text of a phone number “03-5533-1001” is arranged in a region A21, and an icon indicating that a call is being made is arranged in a region A31. The first information in this example is that the second user is “ABC pizza”, the phone number of another phone device is “03-5533-1001”, and a call is in progress.

The second image D2 indicates second information related to the second user including information other than the first information. The image generation unit 120A generates the second image D2 based on the identification information ID. The image generation unit 120A specifies the address of the second user based on, for example, the phone number or the name of the second user. For example, the image generation unit 120A uses a web browser to search for the address based on the phone number or the name of the second user so as to specify the address of the second user. Furthermore, the image generation unit 120A may use a map application to generate an image of a map including the specified address, and may use the image of the map as the second image D2. In this case, the second image D2 may be a map in which the position indicating the address of the second user is the center. By locating the address of the second user at the center of the map in this manner, it is possible to notify the first user of the situation around the address of the second user. In addition, for example, the image generation unit 120A may use a web browser to search for the address based on the phone number or the name of the second user so as to specify a service provided by the second user, generate an image related to the specified service, and set the image as the second image D2.

FIG. 6 is a plan view illustrating an example of the second image D2 displayed on the display surfaces 41S and 42S of the display device 14. In the second image D2 illustrated in FIG. 6 , an image of a map including the address of the second user is arranged in a region B11, an image indicating a street view of the address of the second user is arranged in a region B21, and an image related to the service of the second user is arranged in a region B31. The second information in this example is the map including the address of the second user, the street view of the address of the second user, and the content of the service provided by the second user. The first user can know the map including the address of “ABC pizza” that is the second user, a menu of “ABC pizza”, and the like only by talking on the phone with the second user.

The detection unit 130 illustrated in FIG. 4 detects a switching operation by the first user to switch the display state of the display device 14 from the first display state to the second display state. Specifically, the detection unit 130 detects that the display state of display device 14 is switched from the first display state to the second display state based on the detection information 18 a.

When the display state of the display device 14 indicated by the detection information 18 a is the first display state, the display control unit 140 causes the display device 14 to display the first image D1. In this example, when the display state of the display device 14 is the first display state, the display control unit 140 displays the first image D1 on the display surface 41S of the display device 14. For example, the display control unit140 displays the first image D1 illustrated in FIG. 5 on the display surface 41S of the display device 14.

Furthermore, when the switching operation is detected by the detection unit 130, the display control unit 140 changes the display state of the display device 14 to the second display state and displays the second image D2 on the display device 14. For example, the display control unit 140 displays the second image D2 illustrated in FIG. 6 on the display surfaces 41S and 42S of the display device 14.

When the first user switches the display state of the display device 14 from the first display state to the second display state, the first user rotates the housing 42 illustrated in FIG. 1A in a direction of an arrow Q. In this change of the display state, it is desirable that the second image D2 is immediately displayed on the display device 14 when the display state of the display device 14 becomes the second display state. When the second image D2 can be prepared while the display state of the display device 14 is the first display state, the second image D2 can be displayed on the display device 14 from the start of the second display state.

Therefore, in a case where a call between the first user and the second user is started while the display state of the display device 14 is the first display state, the image generation unit 120A generates the second image D2. Specifically, when communication is established between the mobile phone device 100A and another phone device, the communication unit 110A outputs the identification information ID to the image generation unit 120A. The image generation unit 120A generates the second image ID based on the identification information ID from the timing of acquiring the identification information ID from the communication unit 110A.

In a case where the display state of the display device 14 is the first display state, the mobile phone device 100A is smaller than that in a case where the display state of the display device 14 is the second display state. Therefore, it is common for the first user to talk with the second user according to the mode for a normal call. In a call at a regular place, the first user holds the mobile phone device 100A with one hand, presses the speaker 16 against the ear, brings the microphone 17 close to the mouth, and makes a call. In a case where the display state of the display device 14 is the first display state, the first user recognizes the phone number or the like of another phone device by viewing the first image D1 when there is an incoming call or a call. After confirming the phone number or the like of another phone device, the first user presses the mobile phone device 100A against the face to make a call.

On the other hand, when the display state of the display device 14 becomes the second display state, detailed information regarding the second user is displayed on the display device 14. For this reason, the first user often talks with the second user while viewing the second image D2 displayed on the display device 14. Therefore, when the display state of the display device 14 is switched from the first display state to the second display state during a call, it is desirable to switch to the hands-free call even if the first user does not operate the operating device 15.

Therefore, when the display state of the display device 14 is the second display state at the timing when the switching operation is detected by the detection unit 130, the communication unit 110A of the present embodiment makes a voice of the second user output from the speaker 16 louder than a voice of the second user output from the speaker 16 when the display state of the display device 14 is the first display state. Specifically, the communication unit 110A makes the amplitude of an audio signal to be output to the speaker 16 in the second display state larger than the amplitude of an audio signal to be output to the speaker 16 in the first display state. Note that, in a case where the speaker 16 includes a plurality of speakers, the speaker that outputs a voice of the second user in the first display state may be different from the speaker that outputs a voice of the second user in the second display state. For example, the speaker that outputs a voice of the second user in the first display state may be the first speaker, and the speaker that outputs a voice of the second user in the second display state may be the second speaker. When the speaker that outputs a voice of the second user is changed according to the display state, it is preferable that the voice of the second user is louder in the second display state than in the first display state. By using different speakers, it is possible to selectively use a speaker for a small volume and a speaker for a large volume.

The image generation unit 120A may notify the communication unit 110A that the generation of the second image D2 is completed. When acquiring the notification, the communication unit 110A may cause the speaker 16 to output a predetermined sound that prompt to change the display state of the display device 14 from the first display state to the second display state. By outputting the predetermined sound from the speaker 16, the first user can know that the second image D2 is ready to be displayed. Note that, in a case where the generation of the second image D2 is completed, in order to notify the first user of the completion, the image generation unit 120A may generate an image prompting a change in the display state, and output the generated image to the display control unit 140. The display control unit 140 causes the display device 14 to display the image. Alternatively, a vibrator may be provided in 100A, and the first user may be notified that the generation of the second image D2 is completed by driving the vibrator. In a case where the notification is made by vibration, when the generation of the second image D2 is completed, the image generation unit 120A may output a control signal for driving the vibrator for a predetermined time to the vibrator.

Next, an operation of the mobile phone device 100A according to the first embodiment will be described. FIG. 7 is a flowchart illustrating an operation of the mobile phone device 100A. The processing device 11 determines whether or not the display state of the display device 14 is the first display state based on the detection information 18 a (step S1). When the determination result of step S1 is negative, the processing device 11 repeats step S1 until the determination result of step S1 is affirmative. When the determination result of step S1 is affirmative, the processing device 11 determines whether a call between the first user and the second user has been started (step S2). The start of the call means that communication has been established between the mobile phone device 100A and another phone device used by the second user. Specifically, the processing device 11 determines that the call has started based on communication information output from the communication device 13.

In a case where the determination result of step S2 is negative, the processing device 11 returns the processing to step S1. On the other hand, when the determination result of step S2 is affirmative, the processing device 11 generates the first image D1 based on the identification information ID (step S3).

Next, the processing device 11 causes the display device 14 to display the first image D1 (step S4). Since the display state of the display device 14 is the first display state, the first image D1 is displayed on the display surface 41S. Since the first image D1 indicates the first information including the phone number of another phone device, the first user can confirm the phone number of another phone device in a state where the mobile phone device 100A is closed. Since the identification information ID in this example includes the name of the second user, as illustrated in FIG. 5 , the first image D1 includes an image “ABC pizza” of the name of the second user located in the region A21 in addition to the image “03-5533-1001” of the phone number located in the region A11.

Next, the processing device 11 generates the second image D2 based on the identification information ID (step S5). The second image D2 indicates the second information including information other than the first information. For example, as illustrated in FIG. 6 , in the second image D2, as information other than the phone number “03-5533-1001” and the name “ABC pizza” of the second user, a map including the address of the second user is arranged in the region B11, and an image indicating the content of the service provided by the second user is arranged in the region B31.

Next, the processing device 11 determines whether or not a switching operation by the first user to switch the display state of the display device 14 from the first display state to the second display state has been detected (step S6). Specifically, the processing device 11 determines whether or not the switching operation has been detected based on the detection information 18 a.

When the determination result of step S6 is negative, the processing device 11 determines whether the call has been ended based on the communication information (step S10). In a case where the determination result of step S10 is affirmative, the processing device 11 ends the processing. On the other hand, in a case where the determination result of step S10 is negative, the processing device 11 returns the processing to step S6.

When the determination result of step S6 is affirmative, the processing device 11 changes the display state of the display device 14 from the first display state to the second display state (step S7). Specifically, the processing device 11 changes the display using only the display surface 41S to the display using the display surfaces 41S and 42S.

Next, the processing device 11 changes the call mode from the normal call to the hands-free call (step S9). Specifically, the processing device 11 increases the amplitude of an audio signal to be output to the speaker 16 as compared with the case of the normal call. By changing to the hands-free call, the first user can talk with the second user while viewing the second image D2 displayed on the display surfaces 41S and 42S. Therefore, since the first user can interact with the second user while referring to the information regarding the second user displayed on the large-screen display device 14, it is possible to communicate with the second user well.

The processing device 11 functions as the image generation unit 120A in steps S1, S2, S3, and S5. The processing device 11 functions as the display control unit 140 in steps S4, S7, and S8. The processing device 11 functions as the communication unit 110A in steps S9 and S10. The processing device 11 functions as the detection unit 130 in step S6.

As described above, the mobile phone device 100A according to the first embodiment includes: the display device 14 capable of switching the display state between the first display state and the second display state in which the display area is larger than the display area in the first display state; the communication unit 110A that executes a call between the first user of the mobile phone device 100A and the second user who makes a call using another phone device; the image generation unit 120A that generates the first image D1 indicating the first information including the phone number of another phone device based on the identification information ID for identifying another phone device, and generates the second image D2 indicating the second information related to the second user including the information other than the first information based on the identification information ID; the detection unit 130 that detects a switching operation by the first user to switch the display state of the display device 14 from the first display state to the second display state; and the display control unit 140 that causes the display device 14 to display the first image D1 in a case where the display state of the display device 14 is the first display state, and changes the display state of the display device 14 to the second display state and causes the display device 14 to display the second image D2 in a case where the switching operation is detected by the detection unit 130.

According to the mobile phone device 100A, since the second image D2 related to the second user is displayed on the display device 14 in the second display state of the large screen, the first user can know information related to the second user during a call. In this case, the first user does not need to perform any input operation on the mobile phone device 100A in order to display the second image D2 on the display device 14. Therefore, operability and convenience of the mobile phone device 100A are improved.

The mobile phone device 100A includes the speaker 16 that outputs a voice of the second user and the communication unit 110A. When the switching operation is detected by the detection unit 130, the communication unit 110A makes a voice of the second user output from the speaker 16 louder than a voice of the second user output from the speaker 16 when the display state of the display device 14 is the first display state.

When the display state of the display device 14 is switched from the first display state to the second display state during a call in the normal call, it is necessary to change the call model to the hands-free call. According to the mobile phone device 100A, in a case where the switching operation is detected by the detection unit 130, the call is changed to the hands-free call, so that the first user does not need to perform any input operation on the mobile phone device 100A. Therefore, operability and convenience of the mobile phone device 100A are improved. In addition, when the display state of the display device 14 is switched from the first display state to the second display state and then is switched again to the first display state during a call, the communication unit 110A may change the call from the hands-free call to the normal call. This is because, in a case where the first user switches to the first display state again, it is considered that the first user intends a normal call by a one-hand operation.

Second Embodiment

The mobile phone device 100A according to the first embodiment described above generates the second image D2 based on the identification information ID. A mobile phone device 100B according to a second embodiment is configured similarly to the mobile phone device 100A according to the first embodiment except that the second image D2 is generated based on the identification information ID and call information X indicating the content of a call. Hereinafter, differences between the mobile phone device 100B according to the second embodiment and the mobile phone device 100A according to the first embodiment will be described.

FIG. 8 is a block diagram illustrating functions implemented by the processing device 11 of the mobile phone device 100B executing the control program PR. By executing the control program PR stored in the storage device 12, the processing device 11 of the mobile phone device 100B functions as a communication unit 110B instead of the communication unit 110A illustrated in FIG. 4 , and functions as an image generation unit 120B instead of the image generation unit 120A illustrated in FIG. 4 .

The communication unit 110B is different from the communication unit 110A that does not output the call information X to the image generation unit 120A in that the identification information ID and the call information X are output to the image generation unit 120B.

The image generation unit 120B generates the second image D2 based on the identification information ID and the call information X output from the communication unit 110B. The call information X indicates the content of a call when the display state of display device 14 is the first display state. Specifically, the image generation unit 120B specifies a keyword included in the call based on the call information X, and generates the second image D2 based on the specified keyword and the identification information ID. The keyword specifying method may be, for example, one or more words included in the utterance of the first user and included in the utterance of the second user. Alternatively, among a plurality of words included in the utterance of the first user and the utterance of the second user, a word that is used most frequently is the keyword.

For example, it is assumed that the first user talks with a doctor who is the second user via an emergency call. In addition, it is assumed that the first user needs to attempt to resuscitate the husband using an AED. FIG. 9 is a plan view illustrating an example of the first image D1 displayed on the display surface 41S of the display device 14. In the first image D1 illustrated in FIG. 9 , an image of text indicating the emergency call is arranged in a region A12, an image of text of the phone number “119” is arranged in a region A22, and an icon indicating that a call is being made is arranged in a region A32. The first information in this example is that the call is an emergency call, the phone number of another phone device is “119”, and a call is in progress.

In addition, it is assumed that the following call is made while the display state of the display device 14 is the first display state.

First user: “My husband is down. He is not breathing.”

Second user: “Is there an AED nearby?”

First user: “I have an AED at hand, but I don’t know how to use it.”

Second user: “How to use an AED is simple. I will explain.”

In this call, the words included in the utterance of the first user and included in the utterance of the second user are “AED” and “how to use”. Therefore, the image generation unit 120B specifies “AED” and “how to use” as keywords. In addition, the image generation unit 120B specifies that the second user is compatible with a video phone based on the phone number “119” indicated by the identification information ID. Further, the image generation unit 120B generates an image related to how to use the AED as a part of the second image D2 by searching based on “AED” and “how to use” using a web browser, for example. Furthermore, the image generation unit 120B generates an image of the doctor who is the second user as a part of the second image D2. The image generation unit 120B generates an image related to a resuscitation method using an AED as a part of the second image D2.

FIG. 10 is a plan view illustrating an example of the second image D2 displayed on the display surfaces 41S and 42S of the display device 14. In the second image D2 illustrated in FIG. 10 , an image regarding how to use the AED is arranged in a region B12, an image of the doctor who is the second user is arranged in a region B22, and an image regarding the resuscitation method using the AED is arranged in a region B32. The second information in this example is how to use the AED, the appearance of the second user, and the resuscitation method using the AED.

Next, an operation of the mobile phone device 100B according to the second embodiment will be described. FIG. 11 is a flowchart illustrating an operation of the mobile phone device 100B according to the second embodiment. The operation of the mobile phone device 100A according to the second embodiment is similar to the operation of the mobile phone device 100A according to the first embodiment except that step S5 a is adopted instead of step S5 illustrated in FIG. 7 .

In step S5 a, the processing device 11 generates the second image D2 based on the identification information ID and the call information X when the display state of the display device 14 is the first display state. The processing device 11 functions as the image generation unit 120B in step S5 a.

As described above, the mobile phone device 100B according to the second embodiment generates the second image D2 to be displayed on the display device 14 based on the identification information ID and the call information X when the display state of the display device 14 is the second display state. Therefore, the mobile phone device 100B can generate the second image D2 in consideration of the content of the call in the first display state. Therefore, useful information is provided to the first user as compared with a case where the second image D2 is generated based on the identification information ID without consideration of the call information X. As a result, the convenience of the mobile phone device 100B is improved.

Note that information displayed in the region B12 and the region B32 may be transmitted from the mobile phone device 100 to the terminal device of the second user. For example, when the second user is a doctor, the information is displayed on the terminal device, so that the doctor can confirm the information displayed on the mobile phone device 100 of the first user. Therefore, the doctor can explain the coping method and the like to the first user more easily by making a call while grasping the obtained information.

Third Embodiment

FIGS. 12A and 12B are perspective views illustrating an appearance of a mobile phone device 100C according to a third embodiment of the present disclosure. The mobile phone device 100C according to the present embodiment is different from the mobile phone device 100A according to the first embodiment in the detailed configuration of the display device 14. In addition, the mobile phone device 100C is different from the mobile phone device 100A in that a communication unit 110C is used instead of the communication unit 110A.

The mobile phone device 100C includes housings 41 and 42 and a hinge 49 as in the first embodiment. In the first embodiment, the mobile phone device 100A has the two display surfaces 41S and 42S. On the other hand, the mobile phone device 100C according to the present embodiment has three rectangular display surfaces 43S, 44S, and 45S. Specifically, the housing 41 has the display surfaces 45S and 44S on its front and back two surfaces, respectively, and the housing 42 has the display surface 44S on one of its front and back two surfaces. The hinge 49 connects a long side of the rectangular end surface 41E of the housing 41 facing the display surface 43S and a long side of the rectangular end surface 42E of the housing 42 facing the display surface 44S.

In the present embodiment, the hinge angle formed by the display surfaces 43S and 44S changes as the hinge 49 rotates. In the present embodiment, by setting the hinge angle to 0 degrees, the user can set the display state of the display device 14 of the mobile phone device 100C to the first display state in which the display surfaces 43S and 44S face each other and display is performed only on the display surface 45S facing outward as illustrated in FIG. 12A. In the present embodiment, by setting the hinge angle to 180 degrees, the first user can set the display state of the display device 14 of the mobile phone device 100C to the second display state in which the display surfaces 41S and 42S face outward and display is performed on both the display surfaces 41S and 42S as illustrated in FIG. 12B. Here, the total display area of the display surfaces 43S and 44S is larger than the display area of the display surface 45S. Therefore, the second display state is a display state in which the display area is larger than that in the first display state.

A first speaker 16 a and a first microphone 17 a that are used when the display state of the display device 14 is the first display state are disposed on a surface of the housing 41 on which the display surface 45S is located. A second speaker 16 b and a second microphone 17 b that are used when the display state of the display device 14 is the second display state are disposed on a surface of the housing 41 on which the display surface 43S is located.

FIG. 13 is a block diagram illustrating functions implemented by the processing device 11 of the mobile phone device 100C executing the control program PR. By executing the control program PR stored in the storage device 12, the processing device 11 of the mobile phone device 100C functions as the communication unit 110C instead of the communication unit 110A illustrated in FIG. 4 .

When the display state of the display device 14 becomes the first display state, the communication unit 110C converts a voice of the first user into an electric signal using the first microphone 17 a, and outputs a voice of the second user from the first speaker 16 a.

When the display state of the display device 14 becomes the second display state, the communication unit 110C converts a voice of the first user into an electric signal using the second microphone 17 b, and outputs a voice of the second user from the second speaker 16 b.

Therefore, when the display state of the display device 14 is the second display state at the timing when the switching operation is detected by the detection unit 130, the communication unit 110C makes a voice of the second user output from the second speaker 16 b louder than a voice of the second user output from the first speaker 16 a when the display state of the display device 14 is the first display state. As a result, even if the first user does not operate the operating device 15, the normal call is switched to the hands-free call.

The mobile phone device 100C according to the third embodiment has the same effect as the mobile phone device 100A according to the first embodiment. In the third embodiment, the display surfaces 43S and 44S face each other in the first display state. Therefore, since a finger or the like of the first user does not touch the display surfaces 43S and 44S, for example, in the first display state, there is an advantage that processing such as disabling the operation on touch panels provided on the display surfaces 43S and 44S is not required.

Fourth Embodiment

An appearance of a mobile phone device 100D according to a fourth embodiment of the present disclosure is similar to that of the mobile phone device 100C according to the third embodiment described with reference to FIGS. 12A and 12B. Functions of the mobile phone device 100D are the same as the functions of the mobile phone device 100C except that a communication unit 110D is used instead of the communication unit 110C and the image generation unit 120B is used instead of the image generation unit 120A.

FIG. 14 is a block diagram illustrating functions implemented by the processing device 11 executing the control program PR. By executing the control program PR stored in the storage device 12, the processing device 11 of the third embodiment functions as the communication unit 110C instead of the communication unit 110A illustrated in FIG. 4 .

The mobile phone device 100D includes the image generation unit 120B described in the second embodiment. Therefore, the mobile phone device 100D generates the second image D2 based on the identification information ID and the call information X. Since this point is the same as that of the second embodiment, the mobile phone device 100D has the same effect as that of the mobile phone device 100B according to the second embodiment. In the fourth embodiment, the display surfaces 43S and 44S face each other in the first display state. Therefore, since a finger or the like of the first user does not touch the display surfaces 43S and 44S, for example, in the first display state, there is an advantage that processing such as disabling the operation on touch panels provided on the display surfaces 43S and 44S is not required.

In short, the image generation units 120A and 120B may generate the second image D2 before the display state of the display device 14 is switched from the first display state to the second display state. For example, in a case where the communication unit 110A makes a call to another phone device or receives an incoming call from another phone device while the display state of the display device 14 is the first display state, the image generation units 120A and 120B may generate the second image D2. Specifically, the communication units 110A and 10B output the identification information ID to the image generation unit 120A in response to a call made to another phone device. Further, the communication units 110A and 110B output the identification information ID to the image generation units 120A and 120B in response to an incoming call from another phone device. The image generation units 120A and 120B may generate the second image D2 based on the identification information ID from the timing of acquiring the identification information ID from one of the communication units 110A and 110B.
